The energy storage part, transmission part, buffer part, release part and mechanical interlocking of the operating mechanism are all integrated into a whole. Only one output interface is connected with the main circuit. The mechanism composition will be fully considered in the design of the mechanism, so that the arrangement of the driving mechanism is reasonable to ensure the minimum deformation of the components. It is convenient to ensure the performance and improve the reliability of the mechanism.
